DualPiP v1.9 Release Notes

DualPiP v1.9 makes Live Captions work on significantly more video sites and streaming platforms. The speech-to-text engine has been completely rebuilt to detect audio sources more reliably, handle encrypted streams, and save bandwidth by downloading only audio data instead of full video files.

• Live Captions on more sites: completely rebuilt speech-to-text engine that automatically detects audio sources from HLS, DASH, and MP4 video streams
• Automatic video stream discovery: detects video manifests and audio URLs by monitoring page network traffic, so Live Captions works even on sites without explicit audio source configuration
• Encrypted video support: Live Captions now works on sites using AES-128 encrypted audio, including more streaming platforms with protected content
• Bandwidth-efficient audio download: extracts and downloads only the audio track from MP4 files instead of the full video, reducing data usage significantly
• TikTok and hotlink-protected sites: automatically adds the correct request headers so audio predownload no longer fails on sites like TikTok that block external requests

• Live Captions no longer shows "downloading…" or "processing…" messages once subtitles have started appearing — only errors are shown
• Audio predownload settings can be updated remotely without requiring an extension update
